  • Charge preamplifier
    Patent number: 9257950
    Abstract: A charge preamplifier for converting an electric charge generated in a charge source sensor into a voltage signal, including: a phase inverting amplifier including an input related to the charge source sensor, and an output for providing the voltage signal; a storage capacitor connected between the input and the output of the phase inverting amplifier; a reset system connected to the input of the phase inverting amplifier, for providing to the storage capacitor a discharging current as a function of a control signal, and a control element including: a first input connected to the output of the phase inverting amplifier, for withdrawing the voltage signal, a second input subjected to a reference voltage, a set of components configured and arranged to generate a control signal proportional to the deviation between the voltage signal and the reference voltage, the proportionality coefficient being lower than one in a high frequency band, an output connected to the reset system to provide thereto the control sign

  • Photodetection cell and laser pulse detector having a cascoded inverting amplifier looped back through a slow follower type feedback
    Patent number: 7053356
    Abstract: Photodetection cell and laser pulse detector furnished with such a cell, as well as laser pulse detection device comprising a matrix of such detectors. The photodetection cell (1) is embodied in the form of an integrated circuit and comprises a photosensor (3) which is able to transform luminous energy received into an electric current and a means (4) for processing the electric current generated by said photosensor (3). Said processing means (4) comprises a cascoded inverting amplifier (5), looped back through a feedback (6) of slow follower type, which is supplied by the electric current generated by said photosensor (3).
